Will my breasts drop and become more rounded at the bottom? 3 weeks post op, 480cc HP saline over muscle (Photo)

Hello,Unfortunately, almost every choice you've made was a poor one.  Your preoperative breast anatomy placed strict limitations on implant size. Although I didn't have the benefit of examining you, based on these photos it is clear your inframammary tissue was very tight an inelastic. What you needed was an experienced surgeon to place appropriately sized implants into meticulously created subpectoral pockets, preferably through an inframammary incision using silicone gel implants.  Your current issues are many, with the most pressing one being double bubble. Almost two decades of experience as a revision breast specialist gives me the confidence to tell you that yours won't 'get better' as you heal.  Your implants are a full inch below your old inframammary fold now, which will not magically disappear with time or implant massage (something that is totally unnecessary in any breast implant surgery, so you may stop massaging immediately).  Your anatomy just doesn't have capacity for a nearly 400 cc implant, and something roughly half the size may be all you can handle. You'll need a revision surgery once you heal. Best of luck!

Thank you for your question. Your plastic surgeon will always be your best resource when it comes to an accurate assessment of your situation, advice, predictions, and/or meaningful reassurance.
Generally speaking, breast implants will "drop" into the pocket that was created during surgery and massaging the implants downward may assist in the dropping of the implants after surgery (for those patients who want to help with the settling of the implants).  The rate of breast implant "settling" may depend on factors such as size of breast implant pocket dissected, tightness of the overlying skin/muscle layers, size of breast implant utilized, and concerns such as pre-existing breast asymmetry.Normally, it takes about 3-6 months (for some patients longer) to see the final result. It is very common for one side to settle faster than the other.For patients considering corrective surgery for tuberous/constricted breasts in the future: Because the breast implants take time to "settle" into the relatively tight tissues of the lower breast poles, it may take several months (six months or even longer) before the final outcome of the procedure is achieved. In other words, patients undergoing this type of surgery should be aware of the need for patience and time before the the  lower breast poles "round out".
Sometimes, one or both breasts implants do not settle as planned and revisionary breast surgery becomes necessary to improve the outcome. On other occasions, if the long-term breast asymmetry is mild ( understanding that absolute symmetry is very rarely achieved), patients will need to decide whether proceeding with revisionary breast surgery is worth the potential downsides associated with additional surgery.
Again, best to follow your plastic surgeon for more specifics. Best wishes for an outcome that you will be pleased with long-term.

Dear dropping of implants is part of the healing process and this occurs after the tissues surrounding the implants slowly relax, allowing the implants to settle into their final position. It can take about four to six months for the implant to drop down to their final position.I understand that you are worried about your implants are not dropping as expected. However, you are still in the early phase of the recovery period. Please do allow some time for the healing process to occur. If after six months, you are not satisfied with the appearance of your breast, you can visit your plastic surgeon and discuss your concerns.Daniel Barrett, MD, MHA, MS
